Abstract	Long Description
	Chapter 173-50 Washington Administrative Code (WAC) establishes the state program for accreditation of environmental laboratories, including labs that analyze drinking water. This WAC chapter was last revised in 2002. One reason for the revision was to adjust the fee schedule to compensate for lost ground due to inflation, in an effort to make the program revenue neutral as the Washington State Legislature intends. Other events dictating the need to revise the WAC were: Establishment of the National Environmental Laboratory Accreditation Program (NELAP). The Department of Health transferring drinking-water accreditation to the state Department of Ecology. Publication of state rules requiring use of accredited labs for analysis of matrices in addition to water. Emergence of a new technology, immunoassay, which is expected to find use in future environmental studies. A revised WAC 173-50 addressing the above issues became effective on November 1, 2002. This version of the Procedural Manual for the Environmental Laboratory Accreditation Program recognizes those revisions.
